Cao Zhen glanced cautiously at Hong Wu, thinking it was unreasonable that Hong Wu couldn't move forward while he could.
What was Hong Wu planning?
Especially after spending some time here, he noticed the mist gradually began releasing poisonous energy. Even he was slightly affected by it, let alone others.
Initially, the mist emitted no poisonous energy; it was clearly because of prolonged exposure that they were now affected.
He could discern why this poisonous energy was present, and surely Hong Wu could as well.
Thus, Hong Wu would inevitably find a way.
Cao Zhen feigned indifference as he walked forward, though his attention remained entirely on Hong Wu behind him.
